In the medium term, gas hydrate reservoirs in the subsea sediment are intended as deposits for carbon dioxide (CO2) from fossil fuel consumption. This idea is supported by the fact, that CO2 hydrates are more stable than methane hydrates at certain conditions. The potential of producing methane by depressurization and/or by injecting CO2 is studied in the frame of the research project SUGAR. ...

Introduction: Type II photodynamic therapy (PDT) is an experimental modality for cancer treatment based on the combined action of a photosensitizing drug (photosensitizer), a special wavelength of light and singlet oxygen (1O2) generation; the cell killing is caused by the reaction of cellular acceptors with 1O2. A mathematical model has been previously developed to incorporate the macroscopic ...

Mechanical product design is crucial in many engineering field and lots of industries. CAE simulation has been widely applied for predicting virtual product design for a few decades to reduce the cost and shorten the design life cycle. Because of complicated geometry, material/geometrical nonlinearity and complex conditions, it is painful to efficiently and accurately simulate and predict ...

Single coil actuators are representing one important component of ABB’s medium voltage reclosers. Their performance is strongly influenced by the considered material properties as well as by the electronic control units’ properties that will power the actuator. Therefore, this paper focuses on electromagnetic actuators modeling and simulation in COMSOL Multiphysics®.

Uncertainty in COMSOL Multiphysics® software simulations due to (a) model parameter uncertainties and (b) mesh-induced truncation errors, is estimated using a design-of-experiments approach [1, 2, 3], and a nonlinear least squares logistics fit method [4, 5], respectively. Examples to illustrate both approaches are given using the COMSOL RF Module (in an application of a MRI coil design) and ...

Microwave discharges have a wide range of applications, such as gas conversion, material processing and surface treatment; also they can provide an efficient way for dissociation of molecular gases as CO2 and N2O. Depending on the operating pressure and temperature, non-equilibrium conditions can be attained within the discharge, where electron temperature, vibrational temperature and ...

We simulated the diffusion of calcium ions through a nanopore created in the cell membrane by electroporation, in presence and absence of the external electric field responsible of the membrane permeabilization. First we solved the set of coupled differential equations that describe the process of ionic diffusion in a 2D nanopore model using the AC/DC Module and the Transport of Diluted Species ...
